PORTER, WILMER VOGT, AND HERBERT E. BARNAR/R'ALL OF ST. LOUIS, MIS- V SOURI ACETYLENE-GAS VGENERATOR Application filed May 2, 1928.

This invention relates to an acetylene gas generator, the general object of the invention being to provide apair of cylinders below the tank, each cylinder containing a tray for holding the carbide, with means for introducing water from the tank into the trays, such means being controlled by the movement of the bell so that the generation of gas is automatically controlled and the trayscan be easily and quickly removed for cleaning and replenishing without interrupting the operation of the device.

Another object of the invention is to pr0- vide disseminators for controlling the flow of gas from the cylinders into the bell so as to produce an even flow of gas, thus eliminating uneven movement of the bell.

A still further object of the invention is to make the device of simple and compact construction so that it can be manufactured to sell at low cost.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts,

to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which a Figure 1 is an elevation of the device.

Serial No. 274,642.

In these views, the numeral 1 indicates the tank for holding the water, said tank being supported by the legs 2 and having the yokeshaped frame 3 connected with its upper end, the uprights of said frame forming guideways for the bell 4 which has the projections 5 I on its upper end engaging the upright portions of the frame. The bell is also provided with the lateral projections 6 adjacent its lower end for engaging the inner walls of the tank, these projections also acting as guiding means for the bottom of the bell and preventing lateral movement of the bell.

A pair of cylinders 8 is supported below the tank, the front end of each cylinder being open and said open end is adaptedto be closed by a cover 9 having a handle 10 attached thereto, the shank of which is threaded and passes through a threaded hole in a cross bar 11 removably supported in the side pleces 12 which project from the sides of the cylinder by having the ends of the cross piece 11 engaging the slots 13 in the side pieces. Thus by turning the handle in the cross piece, the cover will be forced tightly against the end of the cylinder to close the same in a gastight manner.

Each cylinder contains a tray 14 of semicircular shape in cross section and each tray is divided into several compartments by the partitions 15 which are of less height than the height of the tray so that when one chamber is filled with water, the water will pass through the next chamber by flowing over the top of the partition.

Pipes 16 have their lower ends connected with the front ends of the cylinders at the top thereof, above the first chambers of the trays and the upper ends of the pipesare connectedwith a funnel 17 which is divided 'into two parts by a partition 18 so that water introduced into one part of the funnel will pass downwardly through one pipe 16 and water introduced intothe other part of the funnel will pass into the other pipe 16.

-A cock 19 is placed in the tank 1 adjacent the top thereof and a hose 20 has one end connected with this cock and its other end is connected to a spent 21 of curved formation and which is attached to a rod 22 which is adjust ably supported by a rod 23 attached to the top of the bell, by a collar 24 and a set screw 25 so that the rod can be adjusted to hold the spout in a position with the water falling into either part of the funnel 17. By connecting the spout with the bell, it willbe seen that when the bell rises, it will carry the spout with it and when the spout is moved above the'water level in the tank,- the flow of.

water will cease, but when the bell drops and the spout moves to a position below the water level in the tank, the flow of water will start again. Thus the flow of water to the carbide in the tray is automatically controlled by the gas entering the bell.

A pipe 26 is connected with the top of each cylinder 8 and" these pipes pass through the bottom of the tankand enter the bell so that the gasgenerated from the carbide in the trays in the'cylinders will pass into the bell. Theflow of gasfrom each pipe is regulated by a disseminator 27 comprising a cylinder having both'ends closed, with an opening in its lower end through which the pipe passes, the notched end of the pipe resting against the "top of Y the cylinder. Perforations 28 are formed in the lower part of the cylinder so that theygas from each pipe will pass into the cylinder through the ports 29 formed by the notches and this gas will pass from the cylinder, through the ports 28, into the bell. These cylinders act to give an even flow of igasl' and prevent uneven movement of the el I v The gas passes from the bell through the pipe 30 which has its upper end opening into the bell adjacent the top thereof and said pipe passes through the bottom of the tank and then upwardly along the outer side of the I tank, with its outer portion bent into U-shape, asshown at 30 and the lower end of this part 30 is connected with the bottom part of a gas purifier'31 which comprises a casing having its lower part of greater dimensions than its upper part and which contains water through which the gas passes to reach the upper part of the casing. The water level in the casing is controlled I by a cock32 and the outlet of gas from the .top part of the casing is controlled by a cock 33. A cockBet is placed in the pipe 30 to control the flow of gas from the generator to the purifier. Water is introduced into the casing" through the pipe 36 which has a casing BT'at its top into which the water is poured, said casing having a tight closure at its upper end in the form of a cap 38. i

I prefer to make the b.ottom 39 of the casing. 31 in such a manner that excess pressure in the purifier will blowout this bottom and thus prevent further damage to the apparatus. I also provide a blow-ofi' pipe 40 which passes through the top of the bell and has its lower end adjacent the bottom of the bell so that when an excess pressure occurs in the bell, the lower end of the pipe 40 will be with water and the chambers in the traysfilled with carbide, by adjusting the spout 21 over one of the chambers of the nozzle 17 and opening the cook 19, water will flow from the tank through the hose 20, tank 21, into the funnel and from the funnel, the water-will pass down through one of the pipes 16 and drop upon the carbide in the first chamber of oneof the trays. Thus acetylene gas will be produced and this gas will pass upwardly through one of the pipes 26-andthrough the cylinder 27 on said pipe intothe belland the gas from the bell will pass downwardly through the pipe 30 and from said pipe will pass into the purifier, where the gas is purified bypassing through the water in said purifier.

The gas is led to the pointof use by'a hose or pipe connected to the cook 33. As the bell rises under the pressure of gas entering the same, it will carry with it the spout 21 so that water will cease to fiow to the carbide when the bell has raised to a cert-ainposition. Then as the bell drops, due to the exhausting of the gases therefrom, water will again be fed a tothe carbide to generate'more gas. After the first chamber in the tray has been filled -used up, the operator moves the spout 21 so that the water will drop into the other part of the nozzle and thus pass through the other-pipe 16 into the second cylinder. He can then remove the tray of the first cylinder and after cleaning the same, fresh carbide is placed in the chambers of said tray and the tray replaced in its cylinder. Thus there is no interruption in the operation of the device. I

It isthought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

It is to beunderstood' that I may make changes in the construction andin the combination and arrangement of the several parts, provided that such changes fall within the scope ofthe appended claim.

What Iclaim' is l An-acetylene gas generating machine comprising a tank, a bell therein, a pair ofcylinders under the tank, a removable tray containing'carbide in each cylinder, an upwardly extending pipe connected to each cylinder, a double funnel connected to the upper ends of said pipes, a rod extending transversely from the bell, a vertically arranged rod ad-- with water, the water will overflow intothe justably connected with the first rod, a curved spout connected With the lower end of the Vertical rod, a cock carried by the tank below the water level therein, a hose connecting the cock With the spout and means for leading the gas generated in each cylinder into the bell.

In testimony whereof I aifix my signature.
